A real Lorentz-FitzGerald contraction

Many condensed matter systems are such that their collective excitations at low energies can be described by fields satisfying equations of motion formally indistinguishable from those of relativistic field theory. The finite speed of propagation of the disturbances in the effective fields (in the simplest models, the speed of sound) plays here the role of the speed of light in fundamental phys...

Gendering psychosis: the illness of Zelda Fitzgerald.

Psychiatric textbooks tend to describe psychosis as it is experienced by men. The well-documented illness of Zelda Fitzgerald illustrates the feminine side of psychosis. The distinctive features of Zelda's illness--its specific precipitants, the timing of its onset, the discontinuities in its course, the pronounced mood swings, the preservation of intellect and of agency, the maintenance of hum...

On Konig-Egervary Square-Stable Graphs

The stability number of a graph G, denoted by α(G), is the cardinality of a maximum stable set, and µ(G) is the cardinality of a maximum matching in G. If α(G) + µ(G) equals its order, then G is a König-Egerváry graph. In this paper we deal with square-stable graphs, i.e., the graphs G enjoying the equality α(G) = α(G 2), where G 2 denotes the second power of G. In particular, we show that a Kö...
